SDK Prometheus HTTP API bindings/client: Quality and Discoverability

[Bartłomiej Płotka]

Hi!

Given PromQL and Prometheus API adoption by many, I wonder if there's a room for improvement around programmatic use of our APIs. However, this space is a bit inconsistent and undocumented.

In Prometheus client_golang we maintain API binding (experimental): https://pkg.go.dev/github.com/prometheus/client_golang/api - but I don't see any other official lib containing HTTP API bindings.

For other langs I see libs in the community e.g. https://github.com/mckang/promql_java_client, https://github.com/anhdat/prometheus4j and so https://pypi.org/project/promql-http-api/

I wonder, is there a passion to:

1. Document existing libraries for each language in Prometheus website?
2. Develop one binding that rule tham all, with the use of https://swagger.io/specification/ and generators?

Kind Regards

Improving the programmatic use of Prometheus APIs sounds like a great idea. Defining an OpenAPI spec and generating SDKs would bring much-needed consistency across languages.

I’m happy to help with defining the spec and generating the code. 

Let’s make it happen!
